Please can you tell me what this weed is. It's root spreads underground and its stem/leaves pop up everywhere. I can't get rid of it by hand and don't know what it's called. Thank you Rachel Wachlarz

I think it might be Russian knapweed, it's a plant I've never seen before so not completely confident. It's an invasive perennial introduced to N America in the late 1800's
